Well i did a system build not to long ago. It was my first build and it went amazingly well. But just recently ive come across a small problem.. i have a Logitech G15 keyboard and a G5 mouse that suddenly quit working. Well i was looking around for solutions because my PS/2 still worked so I knew it was something with the usb ports. So i booted up one time and on my pre bios screen it lists my IRQ numbers and i noticed that my networking device and multimedia device x2 both had the IRQ number of 5... that raised a couple eyebrows for me so i thought id try to figure how to fix that. Haha easier said than done though. if anyone has ANY solutions to this problem i'm willing to do anything and everything to get this fixed. A few side items that might help ( I get the error usb device has malfunctioned on my windows GUI) ( Its windows vista home premium sp1 ) ( system specs are as followed ) ( Nvidia 750i SLI mobo ) ( Intel pentium core duo ) ( 2 sticks of 2gb corsair ram ) ( Ultra X3 750 watt psu ) ( 750 seagate hard drive ) ( Liteon DVD drive ) ( trend net wireless card ) ( creative sound card ) if any thing else you need to ask me or want to talk to me person to person ill be on aim and myspace AIM - Zachisfatt Myspace - .com/ihaveasg thank you so much just for reading.
